@Nuxwin thank you so much in advance. Really appetiate it
Found a small typo error during digging. Currently it is:
but I guess it should be ($rootGName instead of second $rootUName):
Also there seems a "," too much at the end of the for after [ $self->{'config'}->{'HTTPD_SITES_ENABLED_DIR'}, $rootUName, $rootGName, 0755 ],.
